To @ZZ whom/ t may concern,.-

Be it known that I, WILLIAM HAECKEL, a citizen ofthe United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Umbrella-Frame, of which the following is a full, clear, and eXact description.

This invention has for its obj ect to provide means adapted to enable an umbrella rib and stretcher connected therewith to be readily detached from an umbrella-frame and replaced when desired. This I accomplish by the means illustrated in the accompanying drawings, in which drawings like characters of reference indicate like parts throughout the views, and in whiche- F igurc 1 is a side elevation, partly in section, of my invention applied to the parts of an umbrella-frame. Fig. 2 is a perspective view of the upper end of a rib provided with a head. Fig. 3 is a perspective view of the lower end of a stretcher attached to a swivelcoupling; and Fig. 4 is a vertical transverse section, enlarged, of the swivelcoupling shown in Fig. 3.

As illustrated in the drawings, l represents an umbrella-rod of ordinary construction, having a runner 2 mounted thereon and connected by means of a swivel-coupling with stretchers 4. The stretchers 4 are pivotally connected, by means of pivot-pins 4a, with lugs 5, i'ixedly secured to ribs 6, The ribs 6 have a threaded engagement at one-end with heads 7, which are pivotally secured, by means of pivot-pins or a wire 7a, with a crown S, fxedly secured to the umbrella-rod. A swivel-coupling 3 secures the inner ends of the stretchers 4 to the runner 2 and comprises a sleeve having an interior thread engaging a corresponding thread formed on the end ofthe stretcher 4 and a swivel connection comprising a stud 3a, connected with a head 3b, preferably by means of a threaded engagement. The head 3b is hinged to the runner 2 by means of a wire 3C, passing through a plurality of members attached thereby to said runner. By means of such construction the inner end of the stretcher 4 may be readily unscrewed and detached from the sleeve 3 ofthe swivel-coupling, and when the stretcher is released from said coupling the upper end of the rib 6 may be readily unscrewed and detached from the head 7, which is pivotally connected to the crown 8, and by reversing the order of such operation a new rib and stretcher may be readily secured to the crown and runner of the umbrella-frame.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with an umbrella-rod, of a crown fiXedly secured thereto, a runner mounted on said rod, a rib provided with a head detachably secured thereto, and hinged to said crown, a stretcher pivotally attached to said rib, and a swivel-coupling connecting said stretcher and runner, substantially as shown and described.

2. The combination with an umbrella-rib, of a head detachably secured thereto by means of a threaded connection, a stretcher pivoted to said rib, and a swivel-coupling detachably secured to said stretcher, substantially as shown and described.

3. The combination with an umbrella-rod, of a crown xedly secured thereto, a runner mounted on said rod, a rib provided with a head detachably secured thereto and pivotally connected with said crown, a stretcher pivoted to said rib, and a swivel-coupling connecting said stretcher and runner, comprising a sleeve having a threaded engagement with said stretcher, a head hinged to said runner, and a pivotal connection between said sleeve and head, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
